All the photos of the car on track and in the official marketing materials show it running on Pirelli slicks. The only really wet part was foxhole, which is why the driver lifted through there, in a car with this level of performance that entire section is usually taken flat out.

This prototype also has a diffuser and front splitter that would never pass a roadworthy test, which makes sense given the downforce numbers claimed at over 2000kg of downforce. The body is also full carbon fibre, the interior is stripped out and there's a roll cage. It's basically a full on race car. The road legal non prototype version is probably aiming for a lap time of around under 7:10, and hopefully aiming to break the production EV record of 7:05.
